Employers require guidance about how to manage their obligations to all their employees, including trans and non-gender confirming employees, those who feel strongly about having ‘single-sex spaces’, and those with particular philosophical or religious beliefs."
Not to mention their obligations to menopausal women. Which Make UK certainly didn't mention.
Both NHS Fife and Leonardo's discrimination cases were sparked because employers failed to recognise the needs of menopausal women. Even though Leonardo had bought into some kind of menopause awareness they still didn't give women the privacy they need to manage menstrual flooding which is a common (not universal) effect of perimenopause, with separate basins as well as toilets. I wonder if "awareness" includes this.
And even when it's just about "wanting to pee" men and women have different need. As they age both men and women get urinary urgency. For women it's associated with menopause (as well as pregnancy and maternity, which is also a protected characteristic, lest we forget) for men it's often prostate. But women always have to sit down, men don't. A man with urgency can use a urinal or stand above a toilet, a woman can't. It's not compatible with women's dignity (or safety or privacy) to have to rush to find a private toilet and without time clean urine off the seat before sitting down (which they shouldn't have to do but if men share the toilets....)
AR seemed to be saying very proudly that his employer had prioritised the preferences (or what his employer imagined to be the preferences) of a very small number of young people who they wanted to recruit over the needs of their female employees and especially older (or pregnant) female employees.
That's age as well as sex (and pregnancy) discrimination.
